[wxPython] connecting interactive command line interface to wxTreeCtrl

wxPython Users

Dear wxPythonistas,

I have been trying without much success to connect the python "cmd" standard
lib command line interface to a wxTreeCtrl without much success. The task
seems simple enough and I'm sure it involves redirecting standard input and
output, however I'm almost positive there are some wxPython specific issues
that I should be addressing. Can anybody give me some pointers? Any feedback
would be much appreciated.

Many thanks,

Shakeeb

## wxCmd_test.py

import cmd
from wxPython.wx import *

class CLI(cmd.Cmd, wxTextCtrl):
    def __init__(self, parent, id, txt, style):
        cmd.Cmd.__init__(self)
        wxTextCtrl.__init__(self, parent, id, txt, style=style)
        self.prompt = '> '
    def do_hello(self, arg):
        print "hello again", arg
    def do_quit(self, arg):
        sys.exit(1)

#~ cli = CLI()
#~ cli.cmdloop()

class MyApp(wxApp):
    def OnInit(self):
        self.frame = wxFrame(NULL, -1, "Hello from wxPython")
        #self.frame.cmd = wxTextCtrl(self.frame, -1, "Your command",
style=wxTE_MULTILINE)
        self.frame.cmd = CLI(self.frame, -1, "Your command",
style=wxTE_MULTILINE)
        self.frame.Show(true)
        self.SetTopWindow(self.frame)
        return true

app = MyApp(0)
app.frame.cmd.cmdloop() # this doesn't work
app.MainLoop()

You could get an idea of how this works by looking at PyCrust.

http://sourceforge.net/projects/pycrust/

PyCrust is an interactive Python environment written in Python.
PyCrust components can run standalone or be integrated into other
development environments and/or other Python applications.

PyCrust comes with an interactive Python shell (PyShell), an
interactive namespace/object tree control (PyFilling) and an
integrated, split-window combination of the two (PyCrust).
